Definitions

  • the present invention relates to an apparatus for conveying a solid or liquid material, especially for charging a shaft furnace.
  • the charging apparatus for a shaft furnace has traditionally consisted of endless conveyors (e.g. dog conveyors).
  • the object of the present invention is to improve the charging of a shaft furnace so as to achieve effective and flexible conveyance of material.
  • the present invention provides a conveying apparatus of the charactor once described, which comprises at least two skips with open tops, where at the upper part of the skip there is, or can be attached a lifting handle, a device for transferring the skips between a filling and an emptying position, the device comprising at least one carriage accommodating at least two skips simultaneously, the device including a lifting device, for raising the skip to the emptying position, having locking bars and locking means for locking the bars into the emptying position, the locking bars being situated in relation to the pouring lip of the skip, on the opposite side of the transverse vertical plane bisecting the center of gravity, in order to tilt the skip around the locking bar when the lifting handle is lowered.
  • a lifting handle fitted pivotably at the upper edge of each skip there is a lifting handle fitted pivotably at the upper edge of each skip, and locking bars have been attached to the skip. It is also possible to fit the locking bars to the lifting handle, in which case the lifting handle extends over the skip edge to its sides and can be attached non-pivotably to the skip. Another feasible alternative is that the attachment point of the lifting handle to the upper edge of the skip pivots at the pouring stage.
  • a detachable lifting handle provides the advantage that no lifting handles need to be fitted to the skip but the lifting handle constitutes a part of the lifting device.
  • a skip carriage 2 accommodating two charging skips 1 moves along rails at the floor level of the raw materials storage. This carriage can be directed to the desired point on the rails by means of a control switch.
  • the skip carriage has one steel charging skip 1 which is filled with the raw material to be charged.
  • the skip carriage 2 with its skip 1 is thereafter driven to a position adjacent to the shaft furnace.
  • the charger attaches the full skip 1 to the cables of the chargelifting device 3 by means of the lifting bar 4.
  • the lifting device is an automatically operated twin-cable bogie which moves along two rails fixed to the ceiling.
  • the lifting bar 4 raises the skip from the carriage to the charging platform, which is at a higher level. Here the lifting bar 4 transfers the skip 1 to a position next to the charge inlet in the side of the shaft furnace 6.
  • the skip is locked by means of pneumatically operated locking levers 5 which lock onto the locking bars 7 at the lower end of the skip. Thereafter the lifting device begins to give slack to the skip, and thereby the skip is tilted under the effect of its shape and weight into the charge inlet of the shaft furnace, and the raw material falls into the furnace.
  • the lifting device 3 raises the emptied skip 1 to an upright position, the locking levers 5 open and the lifting device returns the empty skip to the same position on the carriage 2 from which the skip was lifted.
  • the charger fills the skip emptied during the previous cycle and drives the carriage 2 back to the position adjacent to the shaft furnace.
  • the charger detaches the empty skip 1 from the lifting device 3, drives the lifting device to the full skip, attaches it, and dispatches the lifting device on its next cycle.
  • the locking lever 5 can have a projection 9 which extends beyond the pivoting point of the lever 5.
  • a cylinder 12 is pivoted at its lower end to the body of the furnace as indicated by reference numeral 11, and the piston shaft 10 of the cylinder 12 is pivotally attached to the projection 9.
